Mount Unzen








 "Mount Unzen actually consists of a group of composite volcanoes located on Japan’s Shimabara Peninsula east of Nagasaki. The area was the site of a major volcanic eruption in 1792.  The massive landslide swept through the city and eventually reached the Ariake Sea, where it set off a tsunami. Most of the estimated 15,000 deaths caused by the event are believed to have resulted from the landslide and the tsunami.  The 1792 eruption served as a reminder to the Japanese people of Earth’s unpredictability. A series of earthquakes and small eruptions at Mount Unzen in the early 1990s escalated fears of another disaster, but that catastrophe never materialized. Still, anxiety has remained over the Mount Unzen volcano because of the dense population nearby and its history of catastrophic events. The volcano was most recently active from 1990 to 1995, and a large eruption in 1991 generated a pyroclastic flow that killed 43 people, including three volcanologists. Volcanic Explosivity Index (VEI):  1 The seismicity was greatest in the period between one year before the eruption and the start of the lava dome extrusion".[1] .

"Mount Unzen is in kyushu,japan and lies between the philippine plate and Eurasian plate.

The Eurasian Plate is a tectonic plate which includes most of the continent of Euasia (a landmass consisting of the traditional continents of Europre and Asia), with the notable exceptions of the Indian Subcontinental, the A, and the area east of the Chersky Range in East Siberia. It also includes Oceanic Crust extending westward to the Mid-Atlantic Ridge and northward to the Gakkel Ridge".[2]


"The eastern side is a boundary with the North Amerian Plate to the north and a boundary with the Phillippen sea Plate to the south, and possibly with the Okhotsk Plate and the Amurian Plate. The southerly side is a boundary with the African Plate to the west, the Arabian Plate in the middle and the Indo-Australia Plate to the east. The westerly side is a convergent boundry with the North American Plate forming the northernmost part of the Mid-Atlantic Ridge, which is straddled by Iceland. The 1973 eruption of Eldfell, the volcano of the Icelandic island Heimaer, caused by the North American and the Eurasian plates pulling apart, is a result of Diergent plate boundary forces".[3]

Your page is 3 quotes and a video? When you're doing research like this identify the questions you would like answered (I gave you these) then find resources that answer them. You don't need this many exact quotes, interpret or restate what you learned from the sources and then give the credit (citations) where it is due. I know you spent some time on this, but it could use a little more "Ashley."
